FIRING-LOCK FOR BREECH-LOADING GUNS.

SPECIFICATION forming part of Letters Patent No. 623,824, dated April 25, 1899.

Application filed September 16,1898. Serial No. 691,065. (No model.)

To ctZl whom it may concern.-

Be it known that I, CARL POHLIT, a citizen of the German Empire, residing at Essen, Prussia,Germany,have invented an Improvement in Firing-Locks for. Breech-Loading Guns, of which the following is a specification.

This invention refers to improvements in safety devices for firing-locks of breech-loading guns, the object of which is to prevent pulling of the trigger as well as the opening of the breech, and it refers in particular to gun-locks in which when the gun is to be fired the hammer is cooked by pulling the lanyard; but it may be applied to other lockssuch, for instance, as those which are cocked by the motion of the breech-handle in opening the breech.

This invention consists,essentially,in a key mounted either in the breech-block or in the arm of the breech-handle, said key being held by a spring in one or the other of two positions and so shaped as to form a stop to the motion of the trigger and of the breech-handle in one of these positions and to release the same in the other position.

This invention will be best understood when described in connection with the annexed drawings, in which- Figure 1 represents a side view of a breech arrangement, showing one form of my improvement in the safety position. Fig. 2 is a horizontal section of Fig. 1, partly in plan. Figs. 3 and 4 are an elevation and a section corresponding to Figs. 1 and 2, respectively, but showing the safety device released. Figs. 5 to 13 are detail views to be described herein- Fig. 15L is a side view showing another form of the invention in the safety position. Fig. 15 is apartial horizontal section of Fig. 14. Figs. 16 and 17 a are side view and a horizontal section corresponding to Figs. 14L and 15, but showing the safety device released. Figs. 18 to 2% are detail views to be described hereinafter.

Referring now to the form of the improvement shown in Figs. 1 to 13, the letter G designates the breech end of the gun; M, the breech-block; N, the screw, with the arm R for operating the breech-block, and A is a shoulder on the screw N. The firing-lock, as shown in Fig. 9, consists, essentially, of the trigger F, turning on the pin f, the tumbler 2, andcockinglever s, which engages the hammer. B is a block inserted within the breechblock M and held in position by the pin f passing through it. This block B, Fig. 10, is recessed to receive a key, which consists, essentially, of a shank D with a collar 7c,(shown in detail Fig. 11,) attached to a handle 0, (shown in detail in Fig. 18,) and a spring E, Fig. 12. These parts are placed together in the following manner: The block B being removed from the breech-block M, the spring E is first inserted into the recess e', Fig. 10, against a shoulder at the outer end of said recess. Then the shank D is passed through and pushed far enough out that the socket Z of the handle O can be pushed over the square end of the shank D, and the handle and shank are then connected by a pin passed through the socket of the handle and through the square end of the .shank. The block B, with the key, is then inserted into the breech-block M, and the pinf (shown in detail in Fig. 7) is placed into its position, so as to secure the block B, the trigger, and the tumbler t. hen the handle C is in the position shown in Figs. 1, 2, and 5, its inner socket Z bearing against the shoulder of the socket m, Fig. 10, the ear 6 is within the recess h, Fig. 10, of the block B, and the arm 0 is beneath the lug b of the block B and above the projection aon the flange A of the breechscrew N, the arm 01 projecting down against the lug g of the trigger F, Figs. 1 and 9. In this position the key cannot be turned, the trigger cannot be pulled, and the breech-screw cannot be turned in the direction of the arrow, Fig. 1. Oonsequentlyfiring the gun and opening the breech are rendered impossible. By pulling out the key as far as the compression of the spring E will admit, turning the handle 0 one hundred and eighty degrees, and then allowing it to be drawn in by the spring the arm 01 takes the position between the lugs I) Z), Figs. 3, 6, and 8, and the ear 6 enters the recess h of the block B. In this position the lug g of the trigger F and the projection to on the flange A are not obstructed, and both the trigger and the breech-screw are free to be movedthat is, the triggercan be pulled back and the breech-screw can be turned. A in odification of this arrangement is shown in Figs. 14 to 24:. In this modification the key is inserted into another part connected to the breeelrblock-namely, to the arm R of the breech-screw. As in the above-described arrangement, the safety device consists of a key with a handle (J, a shank D, and a crankshaped arm (2 at the inner end of the shank D. At its outer end this arm d has a cylindrical lug d, and its motion is limited to ninety degrees. In the extreme positions an ear 6 of the handle 0 of the key enters one or the other of two recesses h 7t, Fig. 24, in the breechscrew arm R, the two recesses being at an angular distance of ninety degrees, and the arm cl is thus locked against-turning. The arm (Z and its lug d in this device perform the functions of the arms d and c of the first-described device. Thus in one position these serve as a stop to prevent motion of the trigger, as well as of the breech-screw, and release them when turned at an angle of ninety degrees. The trigger F is provided with a socket s. \Vhen the key is locked in the position shown in Figs. 14, 15, and 18, then the lug d of the arm d is within the socket s of the trigger, thereby forming a stop to the motion of the trigger and to the motion of the lock-screw or its arm R. \Vhen, however, the key is pushed out, so as to withdraw the lug (Z from the socket s, and then turned ninety degrees and allowed to be locked in this position by the ear 6 entering the corresponding recess in the arm R, the obstruction to the motion is removed and the trigger F, as well as the lock-screw, is released. The first or safety position is shown in Figs. 14, 15, and 1S and the position for firing in Figs. 16, 17, and 19. Fig. 20 is a side elevation and end elevation of the key-shank D with its crank-arm (Z and cylindrical lug d; Fig. 21, elevations of the trigger F, showing the socket s; Fig. 22, the,

handle of the key; Fig. 23,

and Fig. 24 shows part of the arm R with the chamber for the key and spring.

What I claim as new is 1. In a breech-fermeture for guns of the character specified, the breech-block M and the locking-screw N mounted in the rear end of the breech-block and embodying the flange A and arm B, said breech-block M and screw N combined With a spring-key inserted into one of said parts, and, when held in one position, engaging the other part, thereby preventing turning of the screw N, While re leasing it in the other position; the key held in position by a spring E and prevented from turning by a stop 6 entering one or the other of the recesses h h and provided with an arm d projecting at right angles from the shank of the key and bearing against the trigger to prevent pulling the same, when the key is in the position to prevent the screw from turning, and releasing the same when the key is in the other position, substantially as described.

2. In a breech-fermeture for guns of the character specified, the combination with the breeclrblock M, breech-screw Nwith flange A and projection a, and trigger F, of a block B inserted into the breech-block M, a pinf for securing the block B Within the breechblock M; a key consisting of a handle 0- with ear 6, arms 0 and cl, and shank D with collar 7c; spring E placed over the shank D between the collar 76 and a collar on the block B; recesses 7L and h and lugs b and Z) on the block B, and lug g on the trigger F, arranged to lock the trigger and the breech-handle in one of the'two positions of the key, and to release them in the other posit-ion, substantially as described.

In testimony that I claim the foregoing as my invention I have signed mynamein presence of two subscribing witnesses.

CARL POIILIT.
